Mixer speed was uncontrollable

Removed screw from back of mixer cover band and then removed the 4 side screws, lifted top off of mixer and removed screws from circuit board control switch, removing wires one at a time so as to install correctly. replaced screws in circuit board/control. Restored top of mixer replaced screws and the put cover band back on mixer.walla done

First I removed the screws that hold the silver band and the top of the mixer (cover). I removed the cover. I then removed the 4 screws that hold the gear housing and removed the housing. I removed the worm gear and removed the bearings and the washer from the "old" worm gear and put them on the replacement worm gear. I took gear grease from the cracked housing and packed the replacement gear with this grease. I attached the gasket to the replacement housing. I placed the attachment gear into the replacement housing and placed the housing over the gear assembly. I then put the mixer back together and ran it for a few minutes to dispurse the gear grease. I just mixed up some bread dough and everything seems to be in working order. I have never done this before so I hope it will continue to function properly.

Gears Stripped on Stand Mixer

Bought a KitchenAid Pro Series stand mixer from Sam's Club about five years ago. The transmission gears stripped. It is failry easy to replace but you need to replace the worm gear and the pinion at the same time. Make sure all the old grease is removed completely to ensure no old shavings reaming in the transmission housing. Also, if you have a fiberglass transmission housing, inspect the housing closely to indetify any hairline fractures and do not fill the transmission assembly with too much grease becasue you need room for the housing to breathe when the unit is in operation. If you fill the housing too much and tighten it, it "WILL" crack the housing. You want enough gree to keep the asssemnly lubricated but not too much that when you run the mixer that it expands and cracks the housing.

Kitchenaid Professional Stand Mixer would rev up quickly and stop working after a few seconds.

I read several stories online explaining that this was a problem with a speed sensor. In order to change the part I removed the motor cover (required removing 3 or 4 screws) and simply unplugged the old sensor from the speed control board and plugged the new one in. Took very little time and minimal effort. Mixer now runs like it did when it was new and cost much less than replacing the entire appliance.

Very happy to find that the new gear housing was metal, not plastic. The whole problem was poor design of plastic to hold metal gears. Removed housing held down by four screws, removed two gears that were damaged. Retaining ring was difficult to remove from retaining slot. New gears replaced the old ones, new retaining ring put in place, new grease packed into all gearing, new stronger metal housing put in place and the Kitchenaid industrial mixer is better than new. Very happy with the parts I purchased.

Nut Screw Plastic Housing Split that stabilizes attachments on top side of machine

I removed the old screw with a hand tool to avoid injuring my hand. I then used my hand to install the new screw. Piece of cake. Ordering from Part Select was was a breeze. The only minor issue was the part cost $4.33 and shipping was $7.25.

I stripped two gears to the power take-off at the head of the mixer using the meat grinder attachment.

I investigated the problem by opening the mixer (four screws) and examining the gear box. Two gears were stripped. I ordered them, using the parts diagram provided. They arrives in about two days. I disassembled the gear box, cleaning out all grease and inspected for further damage. The gears and housing were completely cleaned with solvent. The transmission was then reassembled and regreased with food-grade grease. The mixer is now reassembled and working well. I was very pleased with the price and simplicity of my repair, versus taking it to a repair shop.

when turned on mixer went full speed for 10 secs. then shut off. when turned off then this repeated. Trouble guide indicates defective speed control.

per e.g. and put cover on and secured screws. Pluged in unit turned it on and it worked for 25 secs then went full speed and shut down.. repeat this several times got same results. Put old unit back in and it worked for 2 days then same results. I now suspect coil on shaft is defective. I'll order that and see. Unless some one knows of another problem.

Erratic speed control

1. Removed the silver name band that encircles the mixer head by removing one philips screw at the rear of the head. 2. There are four philips head screws under the band. 3. Remove the four screws and lift the top half of the head from the machine. 4. Looking at the rear of the machine, the speed control is to the right (identify by the speed control knob. 5. Remove the two screws (philips) on each side of the speed control assembly. 6. Lift the speed control from the machine and let it hang by the connecting wires. 7. One at a time, remove the plugs that are connected to the speed control module and place then in the same location as the new part. 8. Set the old control aside. 9. Set the new controller in place and secure with the two philips screws removed during disassembly (note: do not over-tighten the screws as the tabs on the controller are plastic and can break if over-tightened). 10. Replace the cover and replace the four screws holding the cover in place and tighten securely. 11. Replace the beauty name place and tighten in place. This whole process took about 6 minutes from start to finish. The mixer now works like new.

broken thumb screw

remove the old screw and screwed the new part in place. I like your link because it shows a picture of the fixture and you can find the part you need real easy. Will order from you again when I need it.

No beater rotation (stops in one place)

Remove the top cover. Loosen the circuit board and remove the gear case. Remove the retaining clip on the gear shaft and remove the gears. Clean the old grease out and relube. reassemble in reverse order . Not a bad job at all.
